Web start questions after updated JRE (7u65)

After the latest JRE update, my departure from the web application no longer works, the update has been associated with JRE 7 day 65 (JRE 7u65). I was able to recreate it on different machines, I get the exception message is very helpful:

JNLPException [category: launch file error: Exception: null: LaunchDesc]

And in the Java Console, I can see the following output:

# Java Web Start Error:

# Could not find class main se.linkon.sabine.clients.sabineclient.invoker.NBRunWrapper in...

Do you have an idea what is wrong? Why the web Starter cannot find class main? This could be a bug in JRE 7u65? I've tried my application with JRE 7u55 and it works smoothly.

Best regards

For me, this problem has been resolved by putting the main pot in a jar that contains the main class.

I had the same problem with an application that uses a wrapper pot that has just a signed JNLP and a manifest with a classpath in the real main container (and anything other than this one pot) but it contains no classes. I was able to solve this problem by adding a few wrapper class files in the jar of wrapper and use one of those as my main class.

I'm unable to identify changes in the release notes of 7u65 that causes this problem though. I also have another application where the packaging has no main class, but it doesn't have the full path. This application does not have this issue.

  • Firefox plant start up after update of Norton 22.5.4.24 - does not start even in safe mode

    Windows XP

    Install Firefox 41.0.1 own - same problem
    Install Firefox 40.0.3 own - same problem

    Incident reports could help us by giving you an individual diagnosis, but if they are accidents of almost instantaneous startup, allow me to mention something that is 'flow' where you have this problem:

    Firefox crashes a few seconds of starting if you have either the Applian Technologies Freecorder and Replay Media Catcher programs in combination with Norton Security software (and possibly other security software).

    If you have either of these Applian programs and it is not essential, try to uninstall it then restart Windows to ensure that none of its components are running.

    Firefox will start normally after that?

    (If you do not uninstall the program, another user said he used msconfig to stop execution at startup and that fixed FlvSrvc.exe. See: https://support.mozilla.org/questions/1086722#answer-789197)

  • I have some coherent questions after update of Firefox that I've not been able to solve.

    My problems come in a bundle and are present or absent, according to the last update. Issues appeared at the start of the madness of quick update (which was very close to me turned to Firefox). Problems remained in line with a number of updates for a few months and then were fixed. They reappear then a certain number of months. Sorry I don't follow the details of which version they are associated with greater care.

    I'm currently under Firefox 12, on Vista Home Premium, Service Pack 2.

    The bundle of issues includes:

    -not being able to open multiple instances of the combustion chamber at a time (uniform)
    -After closing Firefox, not being only unable to re - open the program without having to re - start my computer (intermittent)
    -If I leave Firefox with the media playing a Web site, sometimes the media continues to play in the background, with no way to stop it (intermittent)
    -modules are behaving erratically. When I open Firefox, I never know what icons module will still be in the toolbar. When I go to put back them into the toolbar, icons are not available in the Customize menu. Sometimes I can not open the page modules in the Tools menu. When I open it, the relevant modules are listed as 'active '. (intermittent)

    Any idea on how I can get Firefox works well again would be greatly appreciated.

    Try to start Firefox in safe mode. This mode disables all extensions, customizations, hardware acceleration, etc., temporarily for the diagnosis and troubleshooting. If Firefox works fine in Safe Mode, then it is probably a problem with the add-on. Restart Firefox in normal mode, and then type "subject: addons" (without the quotes) in the address bar. Disable your extensions, restart Firefox between each one, until you find the troublemaker.

    The issue of not being able to reopen after closing Firefox is usually caused by an add-on that is faulty. safe mode is an easy way to tell if this is the case.

  • Laptop HP Pavilion 2320DX g4: computer hp laptop pavilion g4 does not start successfully after update and return to windows 8.1

    Hi, I have recently updated my laptop to Windows 10. He had so many problems and I didn't like it at all, so I just returned my laptop to Windows 8.1.  Since then, my laptop does not correctly every time, and the fan immediately starts to work as well. I can start my pc and connect to my home screen each time.  If the tile is moving or light up when I move my cursor, then I know that I can use my laptop for a little while. It can freeze after getting out a good program. Other times when I start my laptop, everything is dead except for logging on my screen. My Windows key on the keyboard does not work most of the time.  If the screen does not respond the first time I turn, as described above, I can't absolutely nothing on my pc. I can't access the search bar by moving the cursor to top right, I can't open the tiles, I can't spend in desktop mode, etc.  Front I upgraded to Windows 10 and downgraded to 8.1 all worked perfectly, because I've updated from 8.0 to 8.1 Windows almost 2 years.  I have a defective battery. in fact I can only use my laptop if it is plugged. My fan is constantly going, but I don't know if it's my loss of battery or what's wrong with my pc now.  I have described my problem in the Microsoft community forum but have had little response that was not helpful. I was told to go to the command prompt and put in DISM: scan now (which also contained letters more than that, but I do not remember all). I followed the instructions and for 2 days, my pc seems to do better. Then he returned to this problem again. I hope you can help me.  If you have additional questions, post here or please email me at [removed personal information]. Thank you!

    @DWESTDEWITT,

    Hello and thanks for the display on the HP support forum.  What you can do at this point that there are several updates released by microsoft and hardware vendors is running the Windows Update Troubleshooter.

    If this fails to solve the problem.  The only option will be to restore the operating system to the previous, until HP gets the drivers so that they can release them on the support page for your laptop for Windows 10.

    Thanks again for posting and have a great day.

  • Cannot start windows after update

    After you install a windows update, my computer cannot start windows, when I boot it.  It seems the windows files.  I don't have a recovery disk (lesson).  I have windows vista, is there anyway to restore windows on my PC other than buying the software.  I confess that I do not download updates often... that is why... It's always trouble.

    Hi, MooreTM,

    Brand and model of your computer, please.  Thank you.

    Start the computer

    Start typing F8

    Select Mode safe mode with networking

    What a load Safe Mode, start > all programs > Accessories > system tools > SafeMode

    Select a date and time before the Windows update that caused the problem

  • interface to lr6 stand alone start changed after update

    I have independent lr6.  The soft-start crashing on me and do not synchronize folders and files and I tried an update on the Help menu.

    I asked to look for updates and and after I updated, the image of the beautiful forest at startup is gone and replaced with a painted face.

    can someone explain what happened here and how to return to the beautiful forest of boot?

    your help would be very appreciated.

    Kind regards

    Hi Nick,

    Dislike for the splash screen is understandable - but no need to go back to older versions. You can change the splash screen for an image of your choice. I created a tutorial showing how to do this (it's written for LR5, but my customization of splash screen has carried over from LR5 LR6 to the LRCC):

    I hope this helps!

  • Windows not start successfully after updating BIOS on Satellite P100-240

    Hi all
    After you install a new version of BIOS my laptop wouldn't start windows xp properly.
    It just freezes in a screen black, I was able to go in safe mode, but then I reinstalled windows and now it's the same problem and I can't go in safe mode as I haven´t went through all the procedures of installation of windows.
    Please help me: I can reset the BIOS to my old?

    I use a satellite P100 - 240 (PSPA3E) and any help would be greatly appreciated.
    Thank you

    Hello

    What version of BIOS you have loaded? Version 4.20?

    Normally it shouldn´t do problems, especially after upgrading your BIOS. May I ask if the version of Windows installed on your machine you´d is on the media recovery or from scratch (from scratch means install with a genuine Windows CD and install the downloaded drivers)?

    If everything fails then send you the machine and let check the laptop on certain shortcomings of the BIOS.

  • Envy 15-j059nr: Envy 15-j059nr would not start Windows after update to win10 now the hard drive is missing

    This system worked before Windows 8.1 it has been upgraded to Windows 10 last year. It's my boyfriends computer and last night it kept getting blue screen dreaded with errors on his hard drive. He kept ignoring. Then, his computer's battery died and when he started upward, he could get a blue screen and act as if it would repair itself and would just start all over again. He was going in a loop. He did not know what he was doing, but searched on the Internet and ended up messing around any more.

    Its installation was 850 GB HD 3 partitions, it was set up as a Raid was one the main C drive, one was the restore disc and the other hides. He changed the disk. He changed a few things in bios too, but I don't know exactly what.

    The problelm I have right now, is that when that I boot without the USB bootable media, I created, I'm stuck at a screen that says there is no startup disk and no installed operating system and press F2 to run Diagnostics. When I run the diagnostics, just fine, no errors.

    When I try to recover, repair, reimage or anything other that to reinstall, it goes back to the screen I mentioned above which does not allow me to do anything about this either, with the exception of past at the command prompt, which is X and not C. I did a dir/w and only seen the windows files are here , but under the users directory, documents and images are empty, so don't know if it's even watch what I think it is.

    When I want to install Windows 10, everything goes smooth and then bam, he wants that pilots. I can't find the drivers for this laptop who don't have the .exe and require installation. This notebook is not a CD/DVD player on it. I don't mind doing a reformat and start all over, if I could recover his pictures on his hard drive. They are his grandfather.

    Help, please!

    Thank you in advance!

    AggieFan378

    You are the very welcome.

    Unfortunately, I woudn't be able to help you with that.

    I'm afraid that the PC is now a useless paperweight because of the BIOS update has failed.  There is usually no recourse other than to replace the motherboard.

    If all goes well, you were able to recover the files before that happened, and if not, get a SATA cable adapter USB and read the hard drive on another PC.

  • Satellite A200 - strange question after updating the graphics driver

    The problem is with the driver Mobile Intel (r) 965 Express Chipset Family. System: Grand VISTA 32 bit Home Premium Service Pack 1. Laptop: Satellite A200.

    I have installed the new driver of this (suggestion by Toshiba TEMPO) source:

    http://CE.computers.Toshiba-Europe.com/innovation/download_driver_details.jsp?id=65340&OSID=26&drive rLanguage = 42 & SOURCE = TEMPO & LNG = 20

    After switching on the computer, the system is constantly asking me ("warning on securities"), whether to execute (open) 3 files: C:\Windows\System32\igfxtray.exe /... hkcmd.exe /... igfxpers.exe. Disabling the option "Always ask before opening the file" does not help. I have to choose the option "Open / cancel / close" to continue the implementation of the windows (an option to switch). Please don't forget that I translated above mentioned communications of poles.

    Answer to the question, I received the support of Intel (r):

    ++ This is not really a problem with our drivers. This is related to the rights of the user/administrator and security functions defined by Windows * Vista. ++

    Yours faithfully,

    Maciej Kochan

    When you install the drivers, you must right click on the EXE file and choose "Run as Administrator".

    You should also temporarily disable your security software or reconfigure it to allow the file system.
    Tools such as AdAware and Spybot spyware removal (or spyware in your Internet Security package tool) may block the file system.

  • Satellite P50T - USB3.0 question after update Win8.1

    I had the bad Win8.1 recent update which gave a blue screen on reboot, but I got it using the restore to an earlier date.
    However, since my USBB3.0 ports have been intermittent. One is almost useless, 2 are intermittent and one is partially intermittent.
    I reinstalled all the drivers a few times, contributing for a few hours, then it restarts. Help to restart a bit also.

    Drivers USB used to be labeled as such, but now seem to be integrated with another. I assumed that they are in the chipset drivers but some say they are now only in Win8.1 itself. Can someone enlighten me on this?

    Also the last 1.2 BIOS .exe file downloaded from the Australian site has instructions in Chinese only. It would be nice to have an English version for an English speaking country. I am aware that the changelog does not have USB in the upgrade, then it will probably not help anyway.

    USB 3.0 drivers are part of the system Windows 8.1.
    Using Win 7, it is necessary to install additional USB 3.0 drivers but since win 8 this isn t the case.

    From my point of few reason why don t USB ports work was the recent Blue Screen fault.
    The BSOD appears due to serious problems of software or hardware failure.

    I'm not quite sure if setting the time system start point would be enough good to get all problems solved I guess where the USB ports are not really defective Toshiba recovery should help solve the problem of m.

    Which from my point of view of a few you should try it

    You cannot install third-party software such as UPS on the ESXi software is used.

    You must download the vMA: https://my.vmware.com/de/group/vmware/details?productId=229&downloadGroup=VMA50
